Steven De Luxe Kaleidoscope - Billions of Designs - Steven Mfg Co, St. Louis, MO. Pat Pending.  Another of my childhood toys is hitting the auction block.  Kaleidoscope is cardboard with a metal eye piece and a plastic lense.  Included two of the original end inserts with colored stones in it.  View is a little opaque with age.  Measures 8 1/2" long.  All original from the 1960's.  Lots of colorful designs on the tube.  Only slight wear and no odors in the cardboard.
